'To'fallachoomit:may concern.'

Be itvknotvn that LERUPERT E. .RUNDELL, la "citiZenio-f ithe United States, residing at ,F.Brooklyn, 'county of ldngs,` kand State of `New Yorin; have invented-.a new and useful lImprovement infGlutchessofswhich the following i is.4 a1 specification.

` This invention relates VAtogan vkimprovement 'in a clutch for cigar machines. IIn `the operaitionljoffresh Work cigar machines, it is lsometimes necessary to'stop the machine at different `points in its cycle ofi. operation .to ieffect adjustments "Vhile such Amachines have'heretofore-been equipped with a device for stopping the machine, these deviceswere not sensitive enough to insure Istoppage of ftheinachi-ne atwthe exactlpointdesired land -itjY haslthereforebeenvnecessary to turn .the

`machine over by hand when adjustment or a seriesofadju'stments is required. The main y objectV ofthepresent invention is to climinate "this fdiificulty and provide a device whereby fthe -machine -may be stopped Aat 'any point lhoweverfclose or Adistant from 26; the initial poi-nt of stoppage it may be. lilith this =andother objects not specifically mentioned 'in view, the `-invention consists in *certain constructions and v'combina-tions.

which =Will be hereinafter fully described IU and 4then Especifically pointed out in the claims hereunto 4appended 'In the accompanying drawings, Which Vform -apart A of` this specification and in WliiclrlikeI characters of reference indicate the, same or like parts, Fig. 1 is a sectional elevation of a device constructed inaccord- Y ance With the inventiong'Fig. 2 is a sectional A illustration of a part of the device shown in-'Fig 1,1With its operating mechanism in a different position; Fig. 3 is a cross-sec tional view taken on the line 3 3 in Fig. 1; Fig. 4 is a cross section taken on the line 4 4 in Fig. 1, Wit-h one of the cam levers omitted; Fig. 5 is a detail view of one of ythe cam levers; and Fig. 6 is a fragmentary sectional view taken on the Vline 6 6 in Fig. 3.

Referring to the drawings, 7 indicates a constantly running power shaft deriving its motion from any suitable source of power. A worm 8 Vis formed on or carried by the povver shaft 7 and this Worm is in mesh with and drives a Worm Wheel comprising` a Worm ring 9 and a ring supporting spider 10 rigidly connected together. The spider 10 -screwf21which also secures to the inner end :Each caanrlevein27zis provided with a recess .2S randiaipin 29,the axis of which is .offset .1921. Serial. No. 478,461.

yhas la hub 11 loosely-mounted onla sleeve 12 .ivhich surrounds a shaft 13, the shaftal'be- `ing the un'achine main, shaft. `and Worm :wheel 9 10 areienclosed 1n a casing 14 constructed in tWmparts bolted or The Worm `8 v otherwise yfastened together, the outeripart -having alshaft supporting hub 15` and carrying a bush 16. Outside of the bush 16=the shaft is provided with 4a hand Wheel 17 secured to the shaft by means of ascreW18. .Thesleeve 12 is provided .with a flange-y19 .and interposed between this flangeandthe outer face of thehub 11 is a thrust'ball beariug20. The'inncr end ofthe sleeve, 12 isheld fast tothe shaft 1S byzmeans oi a 70 of the sleeve a spider 22 always rotatable with the shaft 13.

Contacting with thefree face of. theavorin ring 9. is a friction plate23 slidably mounted on a shoulder of the spicle1:,22. This fric tion plate'is normally held inV contact .'tvith .the worm ring 9.by means of :a series of spring bolts A24, passing thro-ughsuitable appertures in the spider z 22 and; of.a .Well 80 ilinowvn type. `The spider.22 furtheri carries a stu-C125 slidablyvengaging a. suitableaper tureV in a Vboss ..26 formed on the friction plate 23 before: referred .to,ftl1e objectof this stud being to relieve the spring bolts `24 from 85 driving stresses.

The friction plate.23 is furtherprovided with a. series :vof concave recesses :,26, l.and in` theserecesses `are located cam levers27.

slightly-from the center of thevscam surface of the lever. .The spider.22 Vfurther carries a seriesxof;adjustable.screws 30 which contact With the pins 29. The free end of each of the cam levers 27 engages a suitable notch of a prong 31 extending from a shifting sleeve 32 slidably mounted on the cylindrical section of the spider 22. The shifting sleeve 32 is provided With an annular slot 100 33 and this slot is engaged by a shifting fork 34, held fast on a shifting rod 35 extending through a bearing 36 to a con venient position in which it may be moved by the machine operator at will..

In Fig. 1, the parts are shovvn in the position they occupy When the machine is running continuously. Then it is desired to stop the machine, the shifting rod 35 is moved as to the left inlFig. 1, and this 110 movement causes the prongs 3l of the shifting sleeve 32 to rock the cam levers 27 and cam the friction plate 23 away from the Worm ring 9. An extremely slight disengaging movement of the friction plate 23 is sufficientto stop the machine, and it Will be readily understood that re-engagement of the friction plate 23 With the Worm ring 9 effects starting of the machine Without shock to its delicate parts. And it Will be further understood that by means of the mechanism described, the machine may be stopped and started for adjustment and other purposes any number of times during the machine cycle of operation, and its operating periods may be as short as desired Without resorting to laborous hand operation.

The particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same; therefore changes and variations may beY made in the structure by Which the invention is carried into effect Without departing from the scope of the claims; and the invention is not to be restricted to the precise details of the particular structure shown and described.

What is claimed is:

l. A clutch comprising a shaft, a Worm wheel rotatable on said shaft and having a flat annular face, a Worm engaging said Wheel, mechanism rotatable with said shaft and provided with a member having a fiat annular face, means for causing normal engagement of said faces, and means for disengaging said faces, said mechanism including a spider fast on said shaft and carrying a series of adjusting devices forming a part of said disengaging means.

2. A clutch comprising a shaft, a Worm wheel rotatable on said shaft and having a flat annular' face, a Worm engaging said Wheel, mechanism rotatable With said shaft and provided with a member having a fiat annular face, means for causing normal engagement of said faces, and means for disengaging said faces, said mechanismincluding a spider fast on said shaft and carrying a series of adjusting screws forming a part of said disengaging means.

3. A clutch comprising a shaft, a Worm Wheel rotatable on said shaft and having a flat annular face, a Worm engaging said Wheel, mechanism rotatable With said shaft and provided with a member having a fiat annular face, means for causing normal engagement of said faces, and means for disengaging said faces, said member being provided With a series of pockets for engagement with said disengaging means.

et. A clutch comprising a shaft, a Worm Wheel rotatable on said shaft and having a flat annular face, a Worm engaging said Wheel,y mechanism rotatable with said shaft and provided with a member having a flat annular face, means for causing normal engagement of said faces, and means for disengaging said faces, said disengaging'means includinga series of cam levers Vengaging said member.

5. A clutch comprising a shaft, a Worm Wheel rotatable on said shaft and having a flat annular face, a Worm engaging said wheel, mechanism rotatable With said shaft and provided with a member having a flat annular face, means for causing normal engagement of said faces, and means for disengaging said faces, said member being pro;

gagement of said faces, and means for dis-pVY engaging said faces, said disengaging means including' fa series ofrcam levers engaging said member,and a device surrounding and movable along said shaft to operate said levers. j

In testimony whereof, I have signed my name to this specification.
